|
|
% Available class options
|
|
% e.g., \documentclass[10pt,conference]{IEEEtran}
|
|
%
|
|
% *** choose only one from each category ***
|
|
%
|
|
% 9pt, 10pt, 11pt, 12pt
|
|
% Sets normal font size. The default is 10pt.
|
|
%
|
|
% conference, journal, technote, peerreview, peerreviewca
|
|
% determines format mode - conference papers, journal papers,
|
|
% correspondence papers (technotes), or peer review papers. The user
|
|
% should also select 9pt when using technote. peerreview is like
|
|
% journal mode, but provides for a single-column "cover" title page for
|
|
% anonymous peer review. The paper title (without the author names) is
|
|
% repeated at the top of the page after the cover page. For peer review
|
|
% papers, the \IEEEpeerreviewmaketitle command must be executed (will
|
|
% automatically be ignored for non-peerreview modes) at the place the
|
|
% cover page is to end, usually just after the abstract (keywords are
|
|
% not normally used with peer review papers). peerreviewca is like
|
|
% peerreview, but allows the author names to be entered and formatted
|
|
% as with conference mode so that author affiliation and contact
|
|
% information can be easily seen on the cover page.
|
|
% The default is journal.
|
|
%
|
|
% draft, draftcls, draftclsnofoot, final
|
|
% determines if paper is formatted as a widely spaced draft (for
|
|
% handwritten editor comments) or as a properly typeset final version.
|
|
% draftcls restricts draft mode to the class file while all other LaTeX
|
|
% packages (i.e., \usepackage{graphicx}) will behave as final - allows
|
|
% for a draft paper with visible figures, etc. draftclsnofoot is like
|
|
% draftcls, but does not display the date and the word "DRAFT" at the foot
|
|
% of the pages. If using one of the draft modes, the user will probably
|
|
% also want to select onecolumn.
|
|
% The default is final.
|
|
%
|
|
% letterpaper, a4paper
|
|
% determines paper size: 8.5in X 11in or 210mm X 297mm. CHANGING THE PAPER
|
|
% SIZE WILL NOT ALTER THE TYPESETTING OF THE DOCUMENT - ONLY THE MARGINS
|
|
% WILL BE AFFECTED. In particular, documents using the a4paper option will
|
|
% have reduced side margins (A4 is narrower than US letter) and a longer
|
|
% bottom margin (A4 is longer than US letter). For both cases, the top
|
|
% margins will be the same and the text will be horizontally centered.
|
|
% For final submission to IEEE, authors should use US letter (8.5 X 11in)
|
|
% paper. Note that authors should ensure that all post-processing
|
|
% (ps, pdf, etc.) uses the same paper specificiation as the .tex document.
|
|
% Problems here are by far the number one reason for incorrect margins.
|
|
% IEEEtran will automatically set the default paper size under pdflatex
|
|
% (without requiring a change to pdftex.cfg), so this issue is more
|
|
% important to dvips users. Fix config.ps, config.pdf, or ~/.dvipsrc for
|
|
% dvips, or use the dvips -t papersize option instead as needed. See the
|
|
% testflow documentation
|
|
% http://www.ctan.org/tex-archive/macros/latex/contrib/IEEEtran/testflow
|
|
% for more details on dvips paper size configuration.
|
|
% The default is letterpaper.
|
|
%
|
|
% oneside, twoside
|
|
% determines if layout follows single sided or two sided (duplex)
|
|
% printing. The only notable change is with the headings at the top of
|
|
% the pages.
|
|
% The default is oneside.
|
|
%
|
|
% onecolumn, twocolumn
|
|
% determines if text is organized into one or two columns per page. One
|
|
% column mode is usually used only with draft papers.
|
|
% The default is twocolumn.
|
|
%
|
|
% compsoc, transmag
|
|
% Use the format of the IEEE Computer Society or IEEE Transactions on Magnetics
|
|
%
|
|
% romanappendices
|
|
% Use the "Appendix I" convention when numbering appendices. IEEEtran.cls
|
|
% now defaults to Alpha "Appendix A" convention - the opposite of what
|
|
% v1.6b and earlier did.
|
|
%
|
|
% captionsoff
|
|
% disables the display of the figure/table captions. Some IEEE journals
|
|
% request that captions be removed and figures/tables be put on pages
|
|
% of their own at the end of an initial paper submission. The endfloat
|
|
% package can be used with this class option to achieve this format.
|
|
%
|
|
% nofonttune
|
|
% turns off tuning of the font interword spacing. Maybe useful to those
|
|
% not using the standard Times fonts or for those who have already "tuned"
|
|
% their fonts.
|
|
% The default is to enable IEEEtran to tune font parameters.

% ***************************

|
|
% IEEE seems to use at least two different values by
|
|
% which ITEMIZED list labels are indented to the right
|
|
% For The Journal of Lightwave Technology (JLT) and The Journal
|
|
% on Selected Areas in Communications (JSAC), they tend to use
|
|
% an indention equal to \parindent. For Transactions on Communications
|
|
% they tend to indent ITEMIZED lists a little more--- 1.3\parindent.
|
|
% We'll provide both values here for you so that you can choose
|

% which one you like in your document using a command such as:

|
|
% determines the height of an invisible strut that is placed
|
|
% *above* the baseline of footnotes after the first. Since
|
|
% LaTeX considers the space for characters to be 0.7\baselineskip
|
|
% above the baseline and 0.3\baselineskip below it, we need to
|
|
% use 0.7\baselineskip as a \footnotesep to maintain equal spacing
|
|
% between all the lines of the footnotes. IEEE often uses a tad
|
|
% more, so use 0.8\baselineskip. This slightly larger value also helps
|
|
% the text to clear the footnote marks. Note that \thanks in IEEEtran

% uses its own value of \footnotesep which is set in \maketitle.
